GIGAR-BAND-FEEDING MECHANISM.

U Application filed December 22, 1920. Serial No. 432,412.

The object of this invention is to provide a feeding device for cigar bands, which de vice is adapted to be attached to, or form a part of a machine for applying cigar bands to cigars.

A further object of this invention is to provide a feeding device for cigar bands which will rapidly and effectively remove successive bands from the bottom of a band stack, removing in each instance the lowermost band in the band stack.

\Vith these objects and other objects which may hereinafter appear in view I have de-' vised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawings forming a part hereof, in which Figure 1 is a front elevation of a portion of a cigar banding machine showing my improved band feeding mechanism,

Figure 2 is a sectional view on the line 22 of Figure 1 looking in the direction of the arrows,

Figure 3 is a sectional view on the line 33 of Figure 2, looking in the direction of the arrows,

Figures 4, 5 and 6 are sectional views of one of the suction members'showing the manner in which the same operates and Figure 7 is a plan view of a portion of the machine showing one of the stack-supporting dogs showing the mechanism for operating one of the dogs.

Throughout the various views'of the drawings, similar characters designate similar parts.

In the preferred embodiment of my invention as disclosed in the accompaying drawings, 1 indicates the table or support of a cigar banding machine.

At 2 and 3 are shown supporting brackets which extend upward from the table and on which is mounted the mechanism for supporting a stack of bands.

Pivotally mounted on each of the brackets 2 and 3 are spaced apart band guides 4 and 5 which are pivoted on rods 7 and are adjustable to and from one another so that they may be separated or brought together to accommodate bands of varying widths and that they likewise may hold the stack, of

bands in. proper alignment. The adjustabilby means of an adjusting screw 7 which threads into bearings 8 on the guides. Ex-

tending upwardly between the band guide members l and 5 is a T-shaped standard 9. There are two of these standards, one of each of the same extending between two of the band guides. These standards also extend down below the table 1 and act as guides for a pair of vertically reciprocating band-picking members 10.

These band picking members lO are arranged to be vertically reciprocated in unison and are provided at their lower ends with pins 11 which extend into slots 12 in the upper end of a bar 13 on which is fixed a roller 14 which rides upon a cam 15 secured on a shaft 16. The shaft 16 is driven from any suitable source and thus rotates the cam 15 which elevates the bar 13 causing the v band picking members 10 to be correspondingly elevated. Elevation of the bar 13 is permitted by reason of the fact that said bar is provided with a slot 17 in which the shaft 16 is movable. The band picking members 10 are provided with upwardly projecting extensions 18, the upper end of which are tapered as at 19.

The band picking members 10 are each provided with a continuous suction port 20 which terminates at the lower end of each of the band picking members 10 in a nipple 21 on which is attached a tube 22 extending from a suction-producing device such as a pump or the like not shown.

The suction ports 20 extend through the band picking members 10 and it will be seen that a band will be held at its ends by the band picking members byreason of the suction exerted therethrou'gh.

As 22 is shown a block which forms an extension of the T-shaped standard 9. Pivotally mount-ed in said block is a dog 23,

said dog being pivoted at 24 and having a finger 25 against which. a spring 26 bears. The spring is seated in a recess 27 in the block and normally tends to thrust the arm 28 of the dog inwardly to cause its finger 29 to rest over the upper end of the band picker 10.

There are two of these dogs, one for each side of the band stack and it will be seen that when these dogs are in their normal position they tend to hold their fingers 29 i above the band picking members and stack of bands to rest on top of said thus sup ort the stack of bands over the band pic ing members 10.

It will'be seen that when these dogs areactuated by mechanism to be described, the

through the block 22 by means of a rocker arm 32 pivoted at 33 in the bracket 2 or 3. The rocker arms 32 are provided with an inwardly extending portion 34, the outer end of which is provided with a tooth 35 which enters into a recess 36 providedin a slide 37 to receive it.

The slide .37 extends through the table 1 and is provided adjacent its lower end, with a laterally extending lug 38. At 39 is shown a bar which is secured on one of the arms 40 'of a bell crank lever pivoted at 41 on a portion. of the machine indicated at 42 in Figure 3. The other arm 43 of the bell crank lever is provided with a roller 44 which rides upon a cam 45 driven in any suitable manner.

' It will be seen that by rotation of the cam 45 the bell crank lever is actuated to cause the bar 39 to be oscillated. When the bar is oscillated downward it contacts with the lugs 38 on the slides 37 and the slides are thus moved downward causing the rocker arms 32 to move inwardly and force the pins 31 through the blocks 22 and thus rock the dogs 23 so that the same carry their fin ers 29 from over the top of the band pic ers 10.

. When this occurs it will be seen that the band stack 30 is allowed to descend and rest upon the upper ends of the band picking members 10.

At 47 are plates secured to the inner faces of the band picking members 10' and slidable behind these plates is a pair of vertically movable plates 48. These plates lie co-extensive with'the band picking members 10 and act to raise the pile of bands so that which the plates 48 act.

the fingers 29 on the dogs 23 can slide under the pile but leave the lowermost band resting upon the band picking members 10. Figures 4, 5. and 6 disclose the manner in ends each of the plates 48 are provided with a lateral extension 49 which is adapted to be coiitacted with by the bar 39 on its oscillating movement.

The band-lifting plates 48 are normally held in their raised position so that their upper ends project slightly above the upper faces of the band picking members 10. (See Figure 4.) To hold the plates in this posi- At their lowertion I provide a spring 50 which attaches '47. (see Figure 3.)

From the foregoing the operation of my improved band feeding mechanism will be readily understood:

The stack of cigar bands 30 is supported between the guides 4 and 5 andrests upon the fingers 29 of the movable dogs 23. The

bar 13 is then raised, bringing the band pickers up with it and causing them to move into contact with the lowermost band in the stack. As the band picking members 10 are brought to their uppermost position,

the bar 39 is moved downwardly and contacts with the lugs 38 on the slides 37 and moves said slides downward causing them to withdraw the fingers 29 of the dogs 23 from under the band stack causing the stack to be supported on the band picking members 10. Figure 4 shows the manner in which the bands are supported at this juncture, and it will be seen that the band stack is supported on the upper ends of the plates- 48. As the bar.39 continues its downward movement it is brought into contact with the lateral projections 49 on the plates 48 and moves said plates downward so that the band stack is permitted .to come into contact with the upper ends'of the band picking members 10. This position is disclosed inFigure 5. As the bar 39 starts its upward movement it releases its pressure on the projections 49 permitting the plates 48 to be drawn upwardly by the springs 50. This upward movement of the plates 48 lifts the band stack 30 as shown, yet permits the lowermost band to adhere to the band pickers 10, being held thereon by suction exerted through the ports 20.

As further upward movement of the bar 39 is continued, this bar releases its pressure on the lugs 38 of the slides 37, thus permitting the dogs to be swung into position with their fingers 29 under the band stack 30 but above the lowermost band which is adhering to the band pickers 10. (See Figure 6.)

A suction conveyor 53 is then slid under the lowermost band which is then supported on the band picking members 10, and the band is caused to adhere to said conveyor while the band picking move downwardly, leaving the band resting upon the conveyor. whichremoves it to a suitable band applying mechanism.
